(6) Parameter setting data register (offset address +9 to +11)
When bit 7 of the parameter type setting register (offset address +8) is set ON, module status (offset address +0) becomes
“30001” (INT type) and “parameter mode” is activated.
The set values of “operation parameter write” mode, “scaling parameter” mode or “offset/gain adjustment” mode are written in
this register.
1) When operation parameter write mode is activated
In this mode, data is set in the locations as shown below, and “operation parameter write mode flag” (bit 4 of the parameter
type setting register) is set ON.
* When using D300win, assign WORD type variables to these registers. If you access by the bit, assign a BOOL type variable
to each bit.
